UKismetMathLibrary::Vector4_Negated
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Returns a copy of A with all four components negated ({-X, -Y, -Z, -W}). Equivalent to the unary minus operator on FVector4.
Caveats & Gotchas
- • W is negated as well. If A represents a homogeneous point (W=1), the result has W=-1, which is not a valid homogeneous point. Use Subtract_Vector4Vector4(Zero, A) only on direction vectors (W=0) if you need to preserve homogeneous semantics.
- • This returns a new vector — A itself is unchanged. In C++ you can also write -A directly on FVector4 without calling this function.

FVector4 Example
Flip a direction vector C++
FVector4 Forward(1.0, 0.0, 0.0, 0.0);
FVector4 Backward = UKismetMathLibrary::Vector4_Negated(Forward);
// Backward == (-1, 0, 0, 0)Version History
